Understanding the stratigraphic architecture of shelf-margin clinoforms is key to determining how sediments are transported to deep-water settings and how the interplay of tectonics (subsidence/uplift) and eustasy, with variation in sediment supply, impacts deep-water sand delivery.

Description
Summary:Understanding the stratigraphic architecture of shelf-margin clinoforms is key to determining how sediments are transported to deep-water settings and how the interplay of tectonics (subsidence/uplift) and eustasy, with variation in sediment supply, impacts deep-water sand delivery. Within this study clinothems are used to establish quantitative and statistical relationships between the shelf-margin architecture, paleoshoreline processes, and deep-water system types (i.e., using quantitative 3D seismic stratigraphy). In the Bight Basin on the southern margin of Australia, the Hammerhead shelf margin prograded during the Late Cretaceous following continental rifting from Antarctica. This understudied interval offers an opportunity to investigate controls on shelf-margin evolution during the early post-rift phase. All available data (2D seismic data, 3D seismic data and well data) from the Ceduna Sub-basin have been integrated to investigate the controls on shelf-margin architecture and factors affecting ... : Open-Access Online Publication: May 29, 2023 ...
